PAPER TRIIIEMING AND PASTING MACHINE.

Specification of Letters Patent.

Patented July 27, 1909.

Application filed September 10, 1908. Serial No. 452,415.

To all whom it may concern:

Be it known that I, GEORGE C. BAUMAN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper Trimming and Pasting Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a paper trimming and pasting machine and more particularly to a paper trimming and pasting ma chine adapted for use in trimming and pasting wall paper or the like preparatory to its application to the wall.

The object of the invention is to provide an exceedingly simple, cheap and durable device for the purpose specified containing a receptacle for the paste and means for spreading the paste upon the back side of the paper while drawing the paper through the machine and trimming the same.

It is also an object of the invention to provide a machine of the class described in which brushes are not used, and in which nevertheless the amount of paste delivered to the paper is limited to the proper amount required for satisfactory application.

It is a further object of the inventionto provide a cross cutting device to enable the paper to be cut exactly to lengths after it is trimmed and pasted.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a fragmentary front elevation thereof.

As shown in said drawings: A indicates a tank or receptacle which may be constructed of cast or of sheet metal, or of any suitable material, and which is designed to contain the paste in suitable consistency and which also serves as the frame or foundation of the machine. The side walls of said tank, as shown, are provided at "each end with upwardly directed arms or brackets aa, in which are provided transverse slots or notches and at the top, in which is journaled at the front end a roller a conveniently constructed of a section of suitable length of soft steel shafting. At the rear end of the machine in the bracket a, a shaft (6 is journaled. This, as shown, is of small size to permit the same to be inserted through the center of a roll of wall paper or the like, and as shown, said shaft is provided at opposite ends with collars a, which hold the paper in operative position on the roll and assist in guiding the same to the knives. On the outer end of the shaft 64 where the same protrudes beyond the yoke ends of the bra ckets a, is threaded or otherwise secured a button or head a which serves to hold the shaft from end movement. Between the middle of said receptacle and said rear shaft or roll is an upwardly extending yoke bracket arm B, adapted to receive the journals for two rollers Z)?), and which, as shown rest one upon the other and between which the paper X, extends. Said rolls may, if de sired, be also constructed of a suitable section of shafting to afford weight and sufficient tension for the paper or may be constructed of wood or any suitable material. Within the receptacle and adjustably se cured on said shafts in any suitable manner, are coacting, peripheral disk knives b b*, which serve to trim the paper as it is drawn therebetween. One of said knives 6*, is secured to a collar which is provided with a set screw and is thereby adjustable on its shaft and the other knife 6 engages the outer side of the disk knife b and is pressed t-hereagainst to make a shearing cut at all times of the spring 6 secured on the shaft between the collar and bracket arm B. Between the front roll a and the trimming rolls is journaled a pasting roll D. This is conveniently constructed of wood and journaled in any suitable manner and the yoke bracket (Z, on each side of the frame prevents end movement of the pasting roll, said roll being of sufficient size to permit the periphery thereof to extend to near the bottom of the receptacle.

Should the roll be of wood or any absorbent material more paste than required might adhere thereto and be carried upwardly by the paper X. For the purpose of preventing this, a scraping blade D, is secured on the frame transversely thereof with its edge bearing against the periphery of the roll, and is held in place by cap screws extending through the transverse slots in said rod or bar, and permit the same to be adjusted from or toward the pasting roll to scrape excess material therefrom.

Means are provided also for cutting the paper transversely when the desired length has been pasted. F or this purpose, as shown, curved arms E, are pivotally engaged on the front end of the machine, one on each side thereof and are connected at the top by means of a shaft 6, extending transversely the machine and also by means of a straight edge or blade 0, rigidly secured between said arms and the inner edge of which is adapted to bear against the front roll a while the paper is being cut transversely. Pivotally engaged to depend from the bar 0, is a sliding cutting head 0 This, as shown, consists of a block or bar slidably engaged on said rod and provided at its lower end is a stud e, on which is journaled a cutting disk 0, and as shown, a handle 6, is provided on said block or bar 6, to permit the knife to be moved transversely the paper for the entire width of the machine. As shown, strong pulling springs c, are connected at the outer ends of said yoke arms E, and to the frame, as shown in Figs. 1 and 2, in a manner such that when the arms are swung outwardly with the spring under tension, the draft of the spring will fall outside of the pivot 6 for said arms, but when said arms are thrown upwardly to' bring the straight edge 0, against the paper on the roll (H, to position the cutter for severing the sheet transversely, the draft of the spring falls inside said pivot pin or screw and hence acts to yieldingly hold the knife against the paper.

The operation is as follows: The shaft a is removed from the machine and inserted through a roll of paper at the aXis and inasmuch as such paper is ordinarily rolled on about a half inch rod, a three-eighths inch rod is preferably utilized for the shaft for said roll. Having secured the roll of paper thereon and returned the flanges a, to place, the roll is dropped into the yoke brackets affording its bearings, the paper is passed over the lower cutting roll o over the pasting roll, and beneath the front roll (4 The upper cuttingroll Z), having been returned to position or placed upon the paper where it passes over the roll 6 a slight pull on the paper around the roll a, serves to draw the roll inwardly rotating the pasting roller 13, and the cutting rolls and serving to simultaneously paste and trim the paper for the desired length. When the desired length of paper for the room height has been pasted and trimmed, the operator swings the arm E, inwardly so that the spring 6, draws the upper ends of the yoke arms E, firmly i11- wardly with'the straight edge 6, bearing against the paper where it is drawn around the roll a The operator now, by means of the handle 6 swlngs the cutter away from the paper and moves the cutter to one of the limits of movement'between the yoke arms, then bracing the same firmly against the paper steel roll, moves the same for the entire width transversely the machine, thus severing the paper by one movement, the straight edge, of course, serving to prevent wrinkling or tearing during the cutting operation, the operation being materially assisted by the rotary wheel which is employed instead of an ordinary knife. As the paper is drawn through the machine the ends are folded back to fold the pasted surfacescate papers by repeated handling hereto- 7 fore necessary and owing to the numerous separate operations that are here combined in the operation of a single machine, he is able to accomplish much more in a given day than has heretofore been possible.

Of course, I am aware that very numerous details of construction may be varied and I therefore do not purpose limiting this application otherwise than necessitated by the prior art.

I claim as my invention:
